Greenbrier Bunker

The Greenbrier Bunker, officially known as Project Greek Island, was a secret United States government continuity facility located beneath the Greenbrier resort in White Sulphur Springs, West Virginia. Constructed in 1958-1961 during the Cold War era, this underground bunker was designed to house the United States Congress in the event of a nuclear attack. The facility remained classified and operational for over thirty years until its existence was revealed by The Washington Post in 1992, after which it was decommissioned and opened for public tours.
